- The present invention relates, in general, to a dental floss casing and, more particularly, to a dental floss casing in which the threads of different kind of floss are wound around two bobbins such that the threads of floss are drawn diagonal to each other, thereby improving convenience of use.
- 2. Description of the Related Art
- Generally, dental floss is one kind of dental cleaning device used to clean the teeth and remove particles of food and dental plaque stuck between the teeth. Dental floss is effectively used either in dental treatment in a dental clinic, or to remove food particles and dental plaque stuck between the teeth after a meal, which is performed by a person who carries it. Thus, the use of dental floss is increasing.
- To be used, the dental floss is contained in a small portable casing (hereinafter referred to as a “box”), which can be carried by a person, and a required length of the thread of dental floss is drawn out of the box and cut using a cutter provided in the box.
- The conventional dental floss box has the structure in which one kind of dental floss, i.e. having e.g. the same thickness, fragrance, additives, or the like is wound around a bobbin, which is provided in the dental floss box in such a way that it is engaged with a bobbin fixer so that the dental floss is forcedly drawn out of the dental floss box.
- However, since the interdental distance and taste may differ for each user, there is a need for a user or users to selectively use a variety kind of dental floss having different thicknesses and additives. However, the conventional dental floss box has only one kind of dental floss, so that it is inconvenient for user(s) to use it to suit to his (their) tastes or teeth structures. Because of such inconvenience, the user(s) should unavoidably carry a plurality of dental floss boxes each having a different kind of dental floss, which is a troublesome task.
- Further, in the conventional dental floss box, since a bobbin fixer for fixing a bobbin around which the dental floss is wound is spaced apart from an inner circumference of a fixing hole of the bobbin, when the thread of dental floss is drawn out of the dental floss box, the bobbin engaged with the bobbin fixer is freely rotated by the drawing force generated when the thread of dental floss is drawn out, so that the thread of dental floss wound around the bobbin may be arbitrarily released, causing the thread of dental floss to either be entangled in the box or to unwind even more.
- Furthermore, while the conventional dental floss box is either entirely semi-transparent or partially transparent, it is very difficult for a user to see into the dental floss box, so that checking the length of the thread of dental floss that remains around the bobbin is not possible.
- Accordingly, the present invention has been made keeping in mind the above problems occurring in the related art, and an object of the present invention is to provide a dental floss casing in which a plurality of bobbins around which the threads of different kinds of dental floss are wound is mounted, and a transparent window is provided in one side thereof so that a user can see into the box therethrough, thereby making it easy to use.

dental floss cutters sections FIG. 6 , even when different kinds of the threads of dental floss are unwound from therespective bobbins respective bobbins bobbins anti-friction member 60. Thus, when the thread of dental floss is released from one of the bobbins, the other bobbin stays stopped, thereby preventing the thread of dental floss that is not at that time being used from being arbitrarily released from the inside of the casing. - In addition, as shown in
FIG. 8 , when the thread of dental floss is drawn, a user holds a distal end of the dental floss and pulls out a required length of it. Then, the user uses thedental floss 52 after cutting it with thecutter 32 by pulling it in the direction of the arrow D. - In the meantime,
FIGS. 9 and 10 are perspective views showing abobbin 50 a that is mounted to thebobbin fixer 40 of the above-mentioned dental floss casing. As shown inFIG. 9 , thebobbin 50 a is configured so thatsidewalls bobbin shaft 53, around which the thread of dental floss is wound. Here, the diameter of the sidewall may preferably be of 1.5 to 3 times the diameter of thebobbin shaft 53. -
FIG. 10 shows the state of twobobbins 50 a having the above construction being fitted around thebobbin fixer 40. - That is, the configuration is such that two
bobbins 50 a are fitted around thebobbin fixer 40 with different kinds of thethreads respective bobbins 50 a. Further, ananti-friction member 60 is more preferably mounted between the two bobbins so that even though twobobbins 50 a, each having twosidewalls bobbin fixer 40, when the thread of dental floss is unwound from one bobbin, the other bobbin is prevented from rotating as may occur because the sidewalls of the twobobbins 50 a are in contact with each other. - The
anti-friction member 60 may be formed of a thin, slippery cellophane film. - The dental floss casing according to the present invention is conveniently used to store and organize dental floss which is used in a dental clinic or by a user to maintain the teeth healthy.
- Particularly, two kinds of dental floss can be used in a single casing, and the manufacturing cost can be reduced by using common parts.
- Although a preferred embodiment of the present invention has been described for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
